A video of French President Emmanuel Macron strongly admonishing a teenager who called him by a nickname is going viral on social media.

A teenager asked Macron "How's it going, Manu?" — using a diminutive for Macron's first name — at a ceremony Monday for the 78th anniversary of Charles De Gaulle's historic appeal for armed resistance against Nazi tyranny.

Macron responded: "Call me Mr. President of the republic or sir." He then added: "The day you want to start a revolution, get a degree and learn to feed yourself, OK? You can start lecturing others then."

Macron tweeted a video of the discussion, sparking a lot of comments Tuesday. Some people criticized the French leader for his perceived arrogance while others approved of his demand for respect.
